Denver requires a Tree Removal Permit from the Office of the City Forester for any tree in the public right-of-way (tree lawn between sidewalk and curb). On private property, removal of healthy trees over 8 inches DBH is discouraged but permit rules vary. Emerald Ash Borer-infested ash trees must be handled per city protocol.
Denver does not operate a formal 'heritage tree' registry, but notable specimen trees in Denver Landmark Historic Districts and on Denver Landmark-designated properties receive enhanced protection through Landmark Preservation. Ordinance 21-1115 expanded tree-related historic protections.
Denver requires 1:1 replacement for any public right-of-way tree removed, using approved species from the City Forester's list. New construction in historic districts or with zoning review must meet landscape planting standards. Fee-in-lieu payments to the Tree Fund are accepted when replanting on-site isn't feasible.
